Usage
Information
IS-IS normally purges LSPs with an incorrect data link checksum causing the LSP source to regenerate
the message. A cycle of purging and regenerating LSPs can occur when a network link continues to
deliver accurate LSPs even though there is a link causing data corruption. This process could cause
disruption to your system operation.
